Title: Magnetic recording and reproducing device
Inventor: BABA TASUKU
IPC: H05K9/00
Filed: 1988-03-28
Abstract: PURPOSE:To prevent switching noises by a method wherein a switching smoothing coil of a switching power source is double shielded with a shield case and a shield member which overlaps the shield case. CONSTITUTION:A switching smoothing coil is hermetically sealed off in a shield case 9 of a tinplate to be shieled to prevent switching noises from jumping into a replaying image signal. But especially concerning a camera incorporated magnetic record reproducer which is microminiaturized more and more, a shielding effect by only the shield case 9 on the smoothing coil is not enough. So that, a shield member 14 (ferromagnetic such as Permalloy or the like) whose shape is identical or nearly identical to that of the shield case 9 is bonded to the part of the shield case 9 which faces a cylinder 11, a head amplifier 13, and flexible wires 15 and 16, where a material of the shield member 14 is different from that of the shield case 9. By these processes, switching noises radiated from the switching smoothing coil 6 are remarkably decreased.
